Attached is a patch that (partially) normalizes the Pathname namestring across all platforms to only contain '/' characters as the directory separators, which is my preferred way to solve the portability problem for pathname serialization. Feeding '' separated paths to Pathname still seems to work.
This work needs:
1. Agreement from others (Alessio, Erik?) that this is the "right" way to solve the problem
2. The MAKE-LOAD-FORM seems to be dumping the Windows version of the path, which means the code is not finished.
3. A convenience function to return the '' separated form for use under Windows.
